WARNING: This page is about a different car, the 2012 Ford Pickup, 2012 Ford F550 Super Duty, 2012 Ford F450 Super Duty, and 2012 Ford Cab & Chassis. However, it is still accessible from the selected car via links, so may be relevant.

G1 CHECK THE PCM FOR DTCS
- Ignition ON.
- Check the PCM for DTCs.
- Are any DTCs present?
- Yes : For DTC P2532 , GO to G2.
  For DTC P2535 , GO to G3.
  
  For all other PCM DTCs, REFER to ELECTRONIC ENGINE CONTROLS - GASOLINE ENGINES -- F250-F550 SUPER DUTY .
- No : The system is operating correctly at this time. CLEAR the DTCs. REPEAT the self-test. TEST the system for normal operation.
G2 CHECK THE RUN START CIRCUIT FOR A SHORT TO VOLTAGE
- Ignition OFF.
- Disconnect: PCM C175B.
- Ignition ON.
- Measure the voltage between PCM C175B-42, circuit CBB52 (GN/WH), harness side and ground
- Is any voltage present?
- Yes : REPAIR the circuit. CLEAR the DTCs. REPEAT the self-test. TEST the system for normal operation.
- No : CHECK for causes of the intermittent fault. ATTEMPT to recreate the hard fault by flexing the wire harness and cycling the ignition key frequently. ACTIVATE other systems in the same wire harness. REPAIR any concern found. REPEAT the self-test. TEST the system for normal operation. If DTC returns. INSTALL a new PCM.
